\title{The GAMLSS add on package for fiting parametric non linear models
}
\description{
The main purpose of this package is to allow non-linear fitting within a GAMLSS model.
 The main function \code{nlgamlss()} can fit any parametric
            (up to four distribution parameters) GAMLSS family of distributions.
